Volcano Monitoring at Yellowstone National Park
The Yellowstone Volcano Observatory monitors volcanic and earthquake unrest in Yellowstone National Park. There are permanent stations that monitor earthquakes, deformation, and hydrologic data in real-time. There are also historic data available from field surveys that are not in real-time. Access to the data is provided below and in the sidebar.
